The Marantz Model 2 is a 40-watt mono tube power amplifier from Saul Marantz's early hi-fi line. A 12AX7 input stage and 6CG7 phase inverter drive a push-pull pair of 6CA7/EL34s, switchable between 40-watt Ultra-Linear and 20-watt triode operation, with two 6AU4GTA heater-cathode rectifiers. It has two high-gain inputs and a preamp input, variable damping, and a built-in meter for bias and balance; owners typically ran two for stereo.
